Re: Conditional actions according to user input

[uzibalqa]

Have been working on an implementation using a case statement.

For the value, I extract the digit part ("-p([[:digit:]])+" "-q([[:digit:]])+")
or else use arg2 as the value for isolated predicates ("-g")

pary=( "-p([[:digit:]])+" "-q([[:digit:]])+" "-g")

for gpn in "${pary[@]}" # Loop through possible short options
do

case $arg1 in
($gpn) _vl="${arg1:2}" ;; # fill _vl for form -[[:alpha:]]+([[:digit:]])
($gpn) _vl="${arg2}" ;; # fill _vl for form -[[:alpha:]]
(*) _vl="" ;; # fill _vl otherwise
esac

done
